Pull EDAC updates from Borislav Petkov:
 "Noteworthy is the NVDIMM support:

   - NVDIMM support to EDAC (Tony Luck)

   - misc fixes"

* tag 'edac_for_4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/bp/bp:
  EDAC, sb_edac: Remove variable length array usage
  EDAC, skx_edac: Detect non-volatile DIMMs
  firmware, DMI: Add function to look up a handle and return DIMM size
  acpi, nfit: Add function to look up nvdimm device and provide SMBIOS handle
  EDAC: Add new memory type for non-volatile DIMMs
  EDAC: Drop duplicated array of strings for memory type names
  EDAC, layerscape: Allow building for LS1021A
